Got one, rate it. Used maybe 8 Mach3 blades in last 2 years. I know it's the same as the "jeans method" (which when I found out about it led me to the Razor Pit) ie stropping but the chances of me doing the jeans method was zero, so RP was £20 well spent. Just for comparisons sake a Mach3 blade used to last me maybe 2 or 3 weeks, say 7 or 8 shaves. So at the most conservative estimate I've quartered my blade expenditure.
